Fountain pen ink smooth in writing

Abstract

The invention relates to fountain pen ink smooth in writing. The fountain pen ink is prepared through mixing the following ingredients in parts by mass: 25-40 parts of cis-1,4-polyisoprene, 1-2 parts of glycol, 1-3 parts of diphenylamine, 2-6 parts of sulfonated lignin, 2-6 parts of p-phenylenediamine, 1-4 parts of triethylene tetramine, 1-2 parts of sorbitol, 1-2 parts of glycerol, 1 part of sodium benzoate, 1-3 parts of carboxylic acid and 40-45 parts of pure water. The ink disclosed by the invention can be smoothly written on paper, is low in ink diffusion, can adapt to the writing of paper of multiple kinds and is good in writing effect.

Description

[0001] Technical field: [0002] The invention relates to the field of ink technology, in particular to a water pen ink with smooth writing. Background technique: [0003] Now more and more people choose to use gel pens, ballpoint pens and other signature pen writing tools.
